doNotCache is true. As a result, Function::New always returns null

It introduces static initializers for the new "MAYBE_BOOL" kind of
flags, which is a no-no for Chrome. This has to be done differently.

2abe14b8f6 HeapProfiler: replace pointer based matching algorithm with string matching algorithm for strings_ member. 
pros: decreased snapshot size.
cons: increased serialization time.

I've tested the implementation on gmail 90mb heap.
I saw no speed degradation on the serialization step.
The snapshot size lost ~3% of its size. 100Mb -> 97Mb.

4f09f42866 MIPS: Improve code generation for the HRandom instruction. 
Port r16684 (e0f70aa)

Original commit message:
Since the per-context random number generator is now
properly seeded upon context creation, we do not need
to check for lazy-initialization anymore, and so we
can implement the HRandom instruction w/o having to
call into the C function (which means we don't need
to MarkAsCall anymore).

5521e2e825 Bugfix: array constructors that expect a type feedback cell that points 
to an AllocationSite were being passed the undefined object in some
cases. Clearly separate the cases where we have an AllocationSite and
where we don't in the general ArrayConstructorStub.
